At the Institute of Energy Technologies – Fundamentals of Electrochemistry (IET-1), we conduct research on cutting-edge topics related to the energy transition and structural change. For example, we are working on the battery of the future and exploring innovative battery concepts. We are also investigating how the greenhouse gas carbon dioxide (CO2) can be transformed from a climate killer into a raw material of the future. The goal of our research and development work is to create cost-effective batteries, fuel cells, and electrolysers with improved energy and power density, longer service life, and maximum safety! Hydrogen production based on renewable energy sources via high- and low-temperature electrolysis is of increasing importance to us.

PhD Position - Design of Experiment and Digital Process Optimization for CO2 Electrolysis
Your Job:
At IET-1, we are studying the electrolysis of CO2 for the sustainable conversion of green energy into chemical energy carriers in order to defossilize the chemical industry. The process control and optimization of electrolysis from the cell to the stack requires automated monitoring, analysis, and control of the operating parameters and processes. As part of this project, high-throughput experimental systems will be enhanced using Design of Experiment (DoE) approaches in order to efficiently explore the high-dimensional parameter space of the electrolysis processes. DoE is essential for data-efficient exploration and optimization of the process parameter space, as well as for adaptive, data-driven machine learning approaches to map the electrolysis process to a digital twin. In parallel, data workflows and system control interfaces (application programming interface, API) are being developed to automate both process monitoring as well as process control. The API-based integration of the digital twin into the process control of the CO2 electrolysis enables autonomous operation of the system, which can differentiate between market-, system- or network-based operating modes depending on requirements.
Your Project Tasks & Structure:
- Development of APIs for electrolysis systems and analysis devices
- Implementation of autonomous process control
- Conceptualization and implementation of degradation models for electrolysis
- Studying performance and degradation of electrolysis in dependence on different operating modes
Your Profile:
- Excellent Master's degree and subsequent PhD in chemical engineering, computational engineering, computational mathematics, data sciences / analysis, system or process engineering, or related fields
- Excellent knowledge of API programming and automation engineering such as LabVIEW and/or EPICS
- Comprehensive knowledge of data science, data analysis, data management as well as machine learning
- Advanced programming skills with python
- Experience with data-driven machine learning (SINDy, LASSO, SISSO packages)
- Basic knowledge of electrochemistry is desirable
- Interest in interdisciplinary research projects and excellent cooperation and communication skills as well as teamworking skills
- Very good command of written and spoken English with extensive vocabulary is required (at least B2 level according to the CEFR), ideally supported by a certificate confirming the language level. In addition, your business fluent German skills round off your profile
